(Optional) Defining Characteristic Information About a Layer 2 Protocol
Context
When non-standard Layer 2 protocol packets with a specified multicast destination MAC address need to be transparently transmitted on the backbone network, define characteristic information about the Layer 2 protocol on the PE. The characteristics of the Layer 2 protocol include the protocol name, Ethernet encapsulation format, destination MAC address, and MAC address that replaces the destination MAC address of Layer 2 protocol packets.
When defining characteristic information about a Layer 2 protocol, do not use the following multicast MAC addresses to replace the destination MAC address of Layer 2 protocol packets:
- Destination MAC addresses of BPDUs: 0180-C200-0000 to 0180-C200-002F
- Destination MAC address of Smart Link packets: 010F-E200-0004
- Special multicast MAC addresses: 0100-0CCC-CCCC and 0100-0CCC-CCCD
- Common multicast MAC addresses that have been used on the device
Perform the following operations on PEs.
Procedure
- Run system-view
The system view is displayed.
- Run l2protocol-tunnel user-defined-protocol protocol-name protocol-mac protocol-mac [ encap-type { { ethernetii | snap } protocol-type protocol-type-value | llc dsap dsap-value ssap ssap-value } ] group-mac { group-mac | default-group-mac }
Characteristic information about a Layer 2 protocol is defined.
- Run commit
The configuration is committed.
